O. Pritchard, Chem. Rev., 55, 745 (1955)) is lower than 2.2 and R is a hydrocarbon radical of alkyl, aryl, cycloalkyl or halogenated ether radical) or a compound having (O-M) -(O-M') -OR linkage (M is defined as above and M can be defined by the same definition given in M). Optionally, a halogen atom, a halogen containing compound, a metal oxide or a metalloid oxide can be added to the above mentioned three component catalyst system as the fourth component to further improve the catalytic properties. The alternating copolymers obtained by this invention are rubber-like in character and can be used as polymeric plasticizers, in adhesives and can be vulcanized with sulfur or a sulfur compound to produce vulcanized elastomers.

BACKGROUND OF THE INVENTION This is a division of application Ser. No. 29,678, filed Apr. 17, 1970 now US. Pat. 3,700,638.

1. Field of the Invention The present invention relates to a process for the production of high molecular weight alternating copolymers of butadiene and a-olefine and to the catalyst used in said process.

2. Description of the Prior Art Because of its chipping and cutting properties and its low skid resistance, the demand for cis-1,4 polybutadiene in the field of automobile tires is not so large as Was expected at first. The defects have been ascribed to its unbranched straight-chain structure. In order to overcome these defects, many attempts have been made to product alternating copolymers of butadiene and wolefine, for example, butadiene and propylene, butadiene and l-butene, etc. However, in general, it is not easy to produce even a random copolymer of butadiene and a-olefine by an ionic catalyst.

For instance, German Pat. 1,173,254 claims a process for preparing a copolymer of conjugated diene and monoolefine using vanadium (V) oxychloride as the catalyst, but the examples do not show a copolymerization reaction of butadiene and propylene. German Pat. 1,144,924 claims a process for preparing a copolymer of diene and ethylene or propylene by using a catalyst system consisting of a compound of Ti, Zr, Ce, V, Nb, Ta, Cr, M0 or W in which the metal is at least in part below a valency of 3. This patent shows the copolymerization reaction of butadiene and ethylene by titanium tetrachloride-lithiumaluminumhydride, titanium tetrachloride-phenylmagnesiumbromide, titanium tetrachloride-sodium dispersion, zirconium tetrachloride-tintetrabutyl and tetraoctyltitanate-phenylmagnesiumbromide catalyst systems in its examples, but a process for preparing a copolymer of butadiene and propylene is not shown. Belgian Pat. 625,657 also describes a process for preparing copolymers and terpolymers of butadiene with ethylene and (or) a-olefines by using a catalyst system containing a hydrocarbon-soluble vanadium compound and an organo-aluminum compound containing more than one organic group having strong sterical hindrance, e.g. 3-methyl-butyl, cycloalkyl or cyclopentylmethyl, and it claims a. process for preparing ethylene-propylene-butadiene terpolymer. However, no example of butadiene-propylene copolymer is shown in it.

On the other hand, British Pat. 1,108,630 shows a process for preparing a rubbery random copolymer of butadiene and propylene of high molecular weight with high content of propylene by using a three components catalyst system consisting of trialkylaluminum, iodine and a compound having the general formula of TiBr Cl., wherein n is zero or an integer of 1. to 4. The microstruo ture of butadiene unit and the content of propylene unit in the copolymer are shown in the patent. But there are shown no experimental results which support the assumption which the copolymer should be a random copolymer of butadiene and propylene. A random copolymer of butadiene and propylene was also prepared by using a catalyst system consisting of triethylaluminum, titanium tetrachloride and polypropylene oxide. Polypropylene oxide was used as a randomizer and therefore a copolymer of butadiene and propylene prepared by the catalyst system of triethylaluminum and titanium tetrachloride was shown to be block-type (paper presented at 2nd Symposium on Polymer Synthesis, Tokyo, Oct. 5, 1968, The Society of Polymer Science, Japan). British Pat. 1,026,615 claims a process for preparing a random copolymer of butadiene and propylene by forming a catalyst system of triethylaluminum and titanium tetrachloride in the presence of propylene, and then adding butadiene to the catalyst system. According to the patent, the propylene content of the copolymer was much higher than that of the copolymer prepared by the catalyst formed after the monomers were mixed. This result is inconsistent with the result described in the above paper. A copolymerization reaction of butadiene and propylene was also carried out by using a catalyst system of triethylaluminum and titanium tetrachloride prepared in propylene and the product was confirmed, by fractional precipitation test, to be a copolymer of butadiene and propylene (Chemistry of High Polymers, The Society of Polymer Science, Japan, 20, 461 (1963)). The content of this paper corresponds to that of the above British Patent, but there is no description in it showing that the copolymer should be a random copolymer of butadiene and propylene.

According to the method of British Pat. 982,708, a mixture containing 8095 mole percent butadiene, the rest being 4-methyl-1-pentene, is polymerized at a temperature in the range 0 to 30 C. by a catalyst system which is the reaction product of vanadium (V) oxychloride with triisobutylaluminum, an aluminumdialkyl monochloride or an aluminum sesquialkyl chloride. The microstructure of the copolymer is not shown in the patent. British Pat. 924,- 654 describes a process for preparing a copolymer of butadiene and propylene by using an Alfin catalyst. The copolymer showed a characteristic infra-red absorption band at 11.95 microns. It was ascribed to tri-substituted ethylene structure. Therefore, the result does not support the assumption that the copolymer should be a random or alternating copolymer of butadiene and propylene.

SUMMARY OF THE INVENTION The object of the present invention is to provide new catalytic systems giving high molecular weight alternating copolymers of butadiene and ot-olefine in high yield.

In accordance with this invention, we have found that by using either one of the catalyst system of 1. an organoaluminum compound-a vanadium compound having V-X linkagea compound having M-OR linkage,

2. an organoaluminum compound-a vanadium compound having VX linkage--a compound having 3. an organoaluminum compounda vanadium compound having VX linkagea compound having MOR linkage-a halogen atom or a halogen compound,

4. an organoaluminum compound-a vanadium compound having VX linkage--a compound having linkage-a halogen atom or a halogen compound,

5. an organoaluminum compounda vanadium compound having VX linkage-a compound having MOR linkage--a metal oxide or a metalloid oxide or 6. an organoaluminum compounda vanadium compound having VX linkagea compound having )x )y'OR linkagea metal oxide or a metalloid oxide high molecular weight alternating copolymers of butadiene and a-olefine can be produced in high yield. The alternating copolymers of this invention are rubber-like in character and can be used as polymeric plasticizers, in adhesives and can be vulcanized with sulfur or a sulfur compound to produce vulcanized elastomers.

Although, contrary to our expectation the microstructure of the butadiene units of all of these alternating copolymers were trans 1,4-configuration, the glass transition temperature of these copolymers is very low and they show rubber-like elasticity. The result coincides with that of the alternating copolymer of butadiene and acrylonitrile (J. Polymer Sci., Part B, II, 411 (1969)). The microstructure of the butadiene unit of the copolymer was trans 1,4-configuration, but the copolymer also showed rubberlike elasticity.

They are also prepared by adding water and then alcohol, alcohol and then water or a mixture of water and alcohol to the compounds having M--R linkage at a suitable conditions and then removing unreacted raw materials and reaction byproducts from the reaction mixture.

In the preferred embodiment the molar ratio of organoaluminum compound which form the first component of the catalyst of the present invention to vanadium compound having V-X linkage which form the second component of the catalyst should be higher than 0.5 (Al/V 0.5).

The preparation of the alternating copolymer of butadiene and ot-olefine is carried out by contacting butadiene with a-olefine in liquid phase in the presence of the catalyst system described above. The copolymerization reaction is generally carried out in the presence of a liquid organic diluent. A suitable diluent that can be used for the copolymerization reaction is a hydrocarbon compound, such as heptane, octane, isooctane, benzene or toluene. The temperature of the copolymerization reaction may be varied from '100 C. to C. and sufiicient pressure is employed to keep the monomers in liquid phase. The molar ratio of butadiene to ot-olefine in the initial monomer composition may be from 20:80 to 80:20 and more preferably is 50:50.

At the completion of the copolymerization reaction the product is precipitated and deashed using a methanolhydrochloric acid mixture. The precipitated product is washed with methanol for several times and dried under vacuum. Thereafter the product is extracted with methyl ethyl ketone and diethyl ether successively. The methyl ethyl ketone soluble fraction is a low molecular weight alternating copolymer and methyl ethyl ketone insoluble and diethyl ether soluble fraction is a high molecular weight alternating copolymer.
